Creating Device Allocations 
The devices have undergone a technical installation.
You now wish to maintain device allocations.
Choose
You branch to the initial screen.
Choose a device location, installation or controlled device.
You can only choose an installation here if the controlled device has been allocated to an installation. You can choose whether the data is to be restricted to the key date or whether the time slice valid for the key date is to be displayed.
Example
An allocation already exists for the device in the unlimited time slice starting on January 1, 1998.
If you execute this function for the key date March 1, 1998 and choose the Prorate indicator, you branch to the new, unlimited contract starting on March 1, 1998. The existing time slice is divided into two time slices, one ending on February 28 and one starting on March 1. You can make changes during the period of the second time slice.
If you execute the function for the key date March 1 without prorating the time slice, you branch to the maintenance screen for the time slice valid on the key date. In the example, the time slice valid on the key date is the original unlimited time slice starting on January 1.
You can also choose Time slices to display a list of time slices, select a time slice from the list or restrict a time slice.
The controlled devices are displayed on the maintenance screen. All of the devices selected are displayed along with the corresponding device relationships.
To make it easier for you to enter new relationships, an empty line is provided for each device and register.
Each device relationship at the register level is also displayed for purposes of information at the device level. If the RV indicator is set, the allocation is valid for all registers of the device.
Enter the controlled device, the allocation type, the controlling device and the attribute for allocation. Choose Enter .
The text for the allocation type and the attribute description are displayed. You can also define allocations for controlled devices at the device level. The allocations at the register level are then automatically generated and displayed. SAP recommends this procedure for devices with many registers. If necessary, you can correct individual allocations after they are generated.
Once you have entered all allocations, save your data.
In the case of sub-annual changes, you must enter meter reading date for controlled metering devices. Choose
Enter a meter reading result for the device on the date of the change.
Save your data.
